My dog loves it. I am waiting to see if it will help with skin issues.

We LOVE the liquid collagen! We have four dogs, all different sizes and ages and each with unique needs. Since adding the collagen to our routine, our senior Dachshunds coat condition has improved and our GSD has been far less itchy. Highly recommend it! Our dogs also really love the yak chews and fish oil.

It's not quite been two weeks since I started my five year old golden on this collagen. I have noticed she is scratching and licking her paws a lot less! Her carpus area (the back of her "ankles" on her front paws) had gotten red and raw and hairless from her constant licking and chewing. They are both pink and healthy again and the fur is growing back! Unfortunately it would not accept my photos that show the improvement :( My 12 year old golden has been on apoquel for quite a few years after trying everything in the book because of her horrible allergies. That's the only thing that worked. I've started weaning her off of it and started the collagen with her too. Fingers crossed it works for her as well! By the way, they LOVE the taste of it. It has actually made them eat more slowly!

This supplement saved me hundreds of dollars before back 40 dogs. My dogs had very itchy skin dandruff and they were constantly itching. There were multiple visits to urgent care getting allergy shots that racked up a lot of money so I was looking for supplements that were healthy, cost-effective and very beneficial for my dog, thankfully, this product was just that my dog’s coat is now really shiny less itching no dandruff and they love it in each meal. I recommend this to every dog.

Yall seem to have products that works.

I'm very satisfied with the products I've ordered!

Shipping was great. Service was excellent. Apparently my dog doesn't like the Yak Chews. Has been on the floor for 2 weeks now.

Love that I found this company! They have Great things for my dogs and Great quality! They also got back to me quickly to answer a question! AAAA++++

great company! I like how much they care for their dogs and therefore i feel comfortable feeding their products to my dogs

Product makes it so easy to give our dog an optimal diet and I can see the results.

These are great chews for my two cattle dogs. They're aggressive chewers and they love these. They're also fun to soak in water and throw in the microwave to make big Cheetos for them once they're almost gone.

Always a smooth experience and my pup is excited every time a Back40 package arrives!

Not too many texts to be annoying

Liquid Collagen is the best!! I love this product! Both of my dogs have benefited from it. Their fur is filling in nicely after a terrible issue with fleas. Their coats are soft and shiny. I am getting ready to place another order.

Love your yaks chews too! Keep Rosey busy.

Back 40 Dogs always goes above and beyond to get my orders to me. Sometimes my orders get a bit mixed up and sent to my post office box, but can't be delivered to my physical address except via UPS and FedEx. . . Back 40 bends over backwards and fixes this very quickly. I can't say enough good about Back 40 Dogs and products that improve the quality of our dog's lives!

I'm please with Back40 Dogs products and service. It's been right on!

Rosey says great chews!

Back 40 Dogs has helped my dog Red so much! The Sea Kelp and Pumpkin Powder are awesome products. Great customer service and easy shipping even all the way to Australia!! We are very repeat customers.

Love the product
